Description
Technical field
The present invention relates to a kind of be used to have flat inserted sheet socket of latch of (flat blade).
Background technology
Japanese unexamined patent discloses and discloses a kind of socket that is used to have the latch of flat inserted sheet for 10-326658 number.This socket is a kind of wall socket, and it is installed in the wall, and front surface is exposed.This socket comprises: housing (case), and it has inserted sheet slot (blade slots) at front surface, is used for inserting the flat inserted sheet of latch; Put reed (blade receiving springs) with a plurality of inserted sheets, it is contained in this housing, is used for putting the flat inserted sheet that is inserted into this housing from the inserted sheet slot, and is electrically connected to from the next electric wire of outside extension.
As shown in figure 28, traditional inserted sheet puts reed 110 and comprises, a pair of reed that is used for toward each other clamping each inserted sheet according to preset distance is to (a pair of spring pieces) 120, is used for the clamping reed to 120 framework (frame) 130.Framework 130 extends 120 back end (in the lower end of Figure 28) from reed.Promptly put in the reed 110 at traditional inserted sheet, near the limit of inserted sheet slot, according to reed to 120 and the order of framework 130 be successively set in the housing.
Figure 29 illustrates the conventional socket 100 that inserted sheet puts reed 110 that has as shown in figure 28, has wherein inserted the front end of the flat inserted sheet 210 of latch 200.As shown in figure 29, for traditional socket 100, when the front end of flat inserted sheet 210 little by little touches the front end (on the top of Figure 29) that inserted sheet puts reed, distance L 100 from housing front surface 101 to latch 200 the shell is long, so that has finger tip and enter into slit between housing and the shell and contact inserted sheet and the danger of getting an electric shock.
A kind of method that prevents such accidental shock is to put reed 110 positions by inserted sheet to move backward, moves backward with the contact point that inserted sheet 210 and inserted sheet are put between the reed 110, as shown in figure 30.In this scheme,, just must reduce framework 130 or reed by the position that mobile inserted sheet puts reed 110 to 120 length if housing does not make an amendment dimensionally.Thus, reed diminishes to 120 elastic force, so that be difficult to keep reed to 120 chucking power and contact pressure.
In addition, reed 120 has a protrusion (not having to show) to be engaged in the hole that forms on the flat inserted sheet 210, is by (for example) " appliances and material safety law (Electrical Appliance and Material Safety Law) " or JIS C 8303 (Japanese Standards Association C 8303) definition from the housing front surface to the distance of protruding the center.Therefore inserted sheet puts the simple mobile of reed 110 positions, and socket just can not satisfy the position of the defined protrusion of regulation.
Once more, traditional inserted sheet puts reed and at reed 120 front end is had guide plate 121, and it opens in advance to be used for guiding reed to the flat inserted sheet between 120.So the length that inserted sheet puts reed is longer, this thickness (highly) that will produce housing becomes big problem.
Summary of the invention
Consider the problems referred to above, the purpose of this invention is to provide a kind of socket, it can prevent accidental shock, and to put reed consistent with being connected pressure and traditional inserted sheet to guarantee chucking power that inserted sheet puts reed, except above-mentioned, it can also reduce the thickness of housing.
The socket that is used for flat inserted sheet latch among the present invention comprises that one has the housing of the slot that is used for inserting flat inserted sheet and covers to be used in the housing putting inserting the inserted sheet the housing and being electrically connected a plurality of inserted sheets that extend the electric wire that comes from the outside from slot at its front surface and puts reed.Each inserted sheet puts reed and comprises that a pair of reed is right, and they are positioned opposite to each other according to preset distance, are used for clamping each inserted sheet; The right framework with being used for fixing reed.Framework comprises: an opposite side sheet (a pair of side pieces), they greater than reed between positioned opposite to each other on the preset distance of distance; Brace (a coupling piece), it is right at side fillet sheet, and bonding pad (a joint piece), and it extends from the right rear end of limit sheet.And reed extends the rear end from the bonding pad on the another side of slot.
That is to say, put in the reed at inserted sheet of the present invention, framework and reed be to according to from beginning to be successively set on the housing near one side of slot, the limit sheet to surpass reed between the preset distance of distance face with each other so that the flat inserted sheet that inserts the housing from slot can not touch the limit sheet.Therefore, flat inserted sheet and inserted sheet move after putting contact point between the reed, so the slit between housing and the frame diminishes when the front end of flat inserted sheet touches reed, can not put finger tip into.So socket of the present invention can stop accidental shock.Because the contact point that flat inserted sheet and inserted sheet put between the reed has moved backward, and do not shorten the length of framework or reed, inserted sheet puts reed can guarantee that chucking power and contact pressure are consistent with traditional reed.
In addition, because inserted sheet of the present invention puts reed by framework (specifically, brace by framework) can guide the flat inserted sheet that inserts housing enter reed between, inserted sheet puts reed and the inserted sheet that has a guide plate at front end traditionally and puts reed and compare and can reduce length.Therefore, this socket can reduce the thickness (highly) of housing.
Preferably, bonding pad from the rear end of limit sheet towards reed to the direction close to each other extension that tilts.Like this, brace can guide the flat inserted sheet that inserts housing enter smoothly reed between.
Preferably, this socket comprises that also a terminal member is to be electrically connected to the electric wire that is inserted into from the external world in the housing, and framework has traditional U-type structure, wherein an edge of the right every limit sheet of limit sheet is connected to each other by brace, and the edge of the another side of the limit sheet that the limit sheet is right is communicated with sheet by one and is connected to terminal member, and the edge of the another side of another limit sheet that the limit sheet is right is a free end, and terminal member and each inserted sheet put reed and use same metallic plate to form through bending process.Like this, can realize that forming terminal member and each inserted sheet effectively with a metallic plate puts reed, and its makes assembling terminal member and each inserted sheet put reed to become easy.
In these cases, preferably extend a reed that is connected to terminal member and have a slit along the latch direction of insertion from a right limit sheet of limit sheet.By forming slit, can realize the structure of a pair of contact, so reed can form excellent contact between the peaceful inserted sheet along the latch direction of insertion.So, if the slit that forms on reed is to extend from free-ended limit sheet, may be difficult to guarantee the chucking power that reed is predetermined, so, the slit that forms on reed is to extend from the limit sheet that is connected to terminal member, thereby may constitute paired contact structure under the situation that does not reduce chucking power.
The structure that inserted sheet puts reed and terminal member is not limited to above-mentioned structure.For example, also preferred framework has traditional U-type structure, an edge of each limit sheet that its limit sheet is right connects by brace each other, and brace is connected to terminal member by being communicated with sheet, another edge of each limit sheet that the limit sheet is right is a free end, and terminal member and each inserted sheet put reed and adopt bending process formation with same metallic plate.
Preferably, reed is not to being parallel setting, so that reed between the free end of distance from the right brace of limit sheet towards the limit sheet narrow down. when flat inserted sheet be inserted into reed between the time, at the reed of limit sheet free end face than opening in that the reed of brace end face is easier. therefore by reed is set non-parallelly, so that the reed of limit sheet free end face (open easily here) between distance narrow than at the brace end face, when flat inserted sheet be inserted into reed between the time, can finely contact between reed pair and the flat inserted sheet.
Preferably, housing comprises: have the main body (body) of the front surface of opening and one and cover at described main body front surface and have the cover plate (cover) of slot at its front surface.Each inserted sheet puts reed and covers in the housing, and at this, reed is to being inserted in the main body, and framework protrudes from the main body front surface.Housing has and prominent puts the rib of the brace of reed to each inserted sheet, and each brace all is supported on this rib.Perhaps, so also be preferred, housing comprises a main body with front surface of opening, with a cover plate that covers the front surface of described main body and have slot on its front surface, each inserted sheet puts reed and covers in this housing, at this, reed is to being inserted in the main body, framework protrudes from the main body front surface, and the brace that each inserted sheet puts reed has protruding rib to main body, and a termination of each rib contacts the front surface of main body.
In this case, when flat inserted sheet was inserted in the housing, rib can bear inserted sheet and put the suffered power of reed, therefore can prevent the distortion of reed.
Preferably, this socket comprises that also one is fixed in the described housing and closes thing.This is not closed thing and closes slot when the flat inserted sheet of latch is inserted in the housing, uses flat inserted sheet to open slot when the flat inserted sheet of latch is inserted in the housing by slot.

Embodiment
Hereinafter, the present invention is described with reference to the accompanying drawings in more detail.
(first embodiment)
Socket according to first embodiment of the invention is a wall socket, and it is installed in the wall and its front surface is exposed.As shown in Figure 1, this socket comprises: housing 1, have two paired slots 12 at its front surface, and be used for inserting the flat inserted sheet 210 of latch 200; Put reed 2 with inserted sheet, it is contained in the housing, is used for putting from slot 12 being inserted into flat inserted sheet the housing 1, and is electrically connected to the electric wire (not providing the figure) that extends from the external world and come.
As shown in Figure 2, housing 1 has the box main body 10 of plastics of opening front surface (upper surface in Fig. 2) and covers at main body 10 front surfaces and have the plastic cover plate 11 of slot 12 at its front surface.Main body 10 and cover plate 11 interconnect by assembling framework 50, and assembling framework is also as the installation frame that mounts the socket on the wall.
Each inserted sheet puts reed 2 and is provided with corresponding to each slot 12, and forms with terminal member 3 integral body, and it is electrically connected to the electric wire that is inserted into housing.The back will be described inserted sheet in detail and put reed 2.
Hereinafter, will describe inserted sheet in more detail and put reed 2.As shown in Figure 3, each inserted sheet puts reed 2 and comprises: a pair of reed 21, and they face with each other within a predetermined distance, are used for clamping each flat inserted sheet 210; With framework 22, it is used for fixing reed to 21.Framework 22 has U-type structure (overlooking from above) haply, and it comprises: an opposite side sheet 23, and they face with each other with the big preset distance of distance than 21 of reeds, can not make it touch the flat inserted sheet that is inserted into housing like this; With brace 24, it is connected to each limit sheet to each edge of 23.Framework 22 also has bonding pad 25 (see figure 1)s, and it extends 23 rear end (lower end among Fig. 3) from the limit sheet on slot 12 another sides.Bonding pad 25 is tilted to down extension from the rear end of limit sheet 23 with direction close to each other, and reed extends from the rear end (lower end) at the brace 25 of the another side of slot 21.
The limit sheet is connected to terminal member 3 to another edge of a limit sheet 23a of 23 by being communicated with sheet 26, and the limit sheet is a free end to another edge of another limit sheet 23b of 23.In other words, the limit sheet is to use the cantilever of brace 24 supports to another limit sheet 23b of 23.
As shown in figs. 1 and 4, each inserted sheet puts reed 2 and is contained in the housing 1, and at this, reed is inserted in the storage groove 14 that forms on the main body 10 21, and framework 22 is from the front surface protrusion of main body.Main body 10 has and protrudingly puts the protrusion rib 15 of the brace 24 of reed 2 to each inserted sheet, and each brace is supported by rib 15.Rib 15 puts and is applied to inserted sheet puts power on the reed when flat inserted sheet 210 is inserted into housing 1, can suppress so inserted sheet puts the distortion of reed 2.
The front surface that the insertion inserted sheet puts the main body 10 of reed is covered by cover plate 11.As a result, put in the reed at the inserted sheet of this embodiment, framework 22 and reed to 21 according to beginning to be set in sequence in the housing 1 from limit near slot 12.
As shown in Figure 1, when the flat inserted sheet 210 of latch 200 when slot 12 is inserted into housing 1, flat inserted sheet 210 contacts 23 with the limit sheet of framework 22, they by the limit sheet to 23 between after carry out contacting 21 with reed.When the front end of flat inserted sheet 210 touches reed to 21 the time, the distance L 1 between the shell of housing 1 front surface and latch 200 is little of inserting finger tip.Therefore, do not worry that finger tip touches flat inserted sheet 210 and the user is shocked by electricity.That is to say, be arranged in the housing 1 because each inserted sheet of this socket puts reed 2, thus framework 22 and reed to 21 according to from beginning order setting near the limit of slot, flat inserted sheet 210 and inserted sheet put between the reed 2 contact point backward (downwards) mobile.Therefore compare with conventional socket 100 shown in Figure 5, when the front end of flat inserted sheet 210 touches reed to 21 the time, distance L 1 between housing 1 front surface and the latch body is littler than traditional distance L 10, as a result of, does not worry that finger tip touches flat inserted sheet 210 and the user is shocked by electricity.
In addition, because the length of the length of framework 22 and reed 21 puts equating of reed with traditional inserted sheet, so this reed 2 can guarantee that chucking power and contact pressure equal traditional inserted sheet and put reed.
With reference to distance L 2 as shown in Figure 5, shown distance from the front surface of housing 1 to the protrusion (not shown) center that is used for being coupled to the hole (not shown) that inserted sheet 210 forms, (L2 is that 11.7mm ± 1mm), the socket of present embodiment can the same distance L 2 that satisfies regulation with traditional socket in JIS.
In this socket, from slot 12 be inserted into the housing flat inserted sheet 210 through the limit sheet to 23 between after, introduce reed smoothly between 23 by brace 25. that is to say, put in the reed at this inserted sheet, the effect of the normal guidance sheet 121 that brace 25 performances of framework 22 are shown in Figure 28, be used for guiding flat inserted sheet enter reed between. therefore, in this socket, unlike common inserted sheet blank film 110 as shown in figure 28, it need not form guide plate 121. as a result of at the right front end of reed, as shown in Figure 6, inserted sheet puts reed 2 and reduces height by eliminating guide plate 121, this is to put reed with the common inserted sheet that has guide plate at the reed front end to compare. as shown in Figure 5, the thickness H100 of this socket and traditional socket 100 compares thickness (highly) H1. that can reduce housing 1
As shown in Figure 7, reed is to a reed of 21, from the limit sheet by connectedness 26 connecting terminal members a limit sheet of 23 extended, and has the opening 27 that the direction inserted along latch is extended.Opening 27 extends to the upper end of bonding pad 25 always from the rear end of a reed.By forming opening 27, can constitute a kind of pair of contact structures, so reed has good contact to 21 peaceful inserted sheets.It should be noted that in this embodiment opening 27 is to form at the spring leaf that extends out from the brace that is connected to terminal member 3.If opening 27 is at another free end and be not connected on the spring leaf that the brace 23b of terminal member 3 extends out and form, be difficult to guarantee the chucking power of being scheduled to for reed 23.So, form opening 27 at the spring leaf that extends out from the brace that is connected to terminal member 3, can under the situation that does not reduce chucking power, form the dual link structure.
As shown in Figure 8, reed is arranged to non-parallel to 21, so that reed narrows down to 23 free end towards the limit sheet to 23 brace limit from the limit sheet to the distance between 21.In other words, reed is to narrower in the distance D 2 of that face of brace than them in the distance D 1 of limit this face of sheet free end between 21.In this embodiment, the limit sheet has only a limit sheet 23a to be connected to terminal member 3 by being communicated with sheet 26 to 23, and the limit sheet is a free end to another limit sheet 23b of 23.At the limit sheet to the reed 21 of this face of 23 free ends (in other words, cantilever this face of free end) than expanding easily at the reed 21 of brace end.Therefore, shown in Fig. 9 A, if reed is parallel to 21, when flat inserted sheet 210 be inserted into reed to 21 between the time, between the reed 21 peaceful inserted sheets 210 of this face of free end, may form the slit, raise so the reliability that connects reduces and unusual temperature may take place.Therefore, by the limit sheet to freely bring in reed between distance D 1 narrow down, the expansion easily of this distance, than the reed of brace between distance D 2 narrow, the contact that reed can produce 21 peaceful inserted sheets 21, shown in Fig. 9 B, when flat inserted sheet 210 is inserted into reed to 21 the time, Jie Chu unfailing performance accesses reinforcement thus.
Inserted sheet puts reed 2, connection sheet 26 and terminal member 3 a usefulness sheet metal as shown in figure 10 and forms by bending process.Inserted sheet puts reed 2 and the same sheet metal of terminal member 3 usefulness when forming in as this embodiment, puts the independently example comparison that forms of parts of reed 2 and terminal member 3 usefulness with those inserted sheets, and the quantity of parts can reduce.Therefore, can reduce cost, and make assembling process become simple.As a reference, if sheet metal has shape as shown in figure 10, preferably form to downcut part at the sheet metal place shown in X zone among Figure 10, it is too little and can not influence the chucking power of reed 21.Downcut part by these, the design of metal die (draft of the metal mold) can increase, and obtains prolonging so can increase the life-span of stamping press and metal die.
The structure that inserted sheet puts reed 2, connection sheet 26 and terminal member 3 is not limited only to above-mentioned structure.For example, they can use configuration as shown in figure 11.In Figure 11, framework 22 has traditional U-type structure, and wherein each limit sheet 23 is connected to each other by brace 24.Brace 24 is connected to terminal member 3 by being communicated with sheet 26, and each limit sheet is free end and curves inwardly 23 the other end.In this embodiment, as shown in figure 12, inserted sheet puts reed 2, connection sheet 26 and terminal member 3 and also forms by bending process with same sheet metal.Compare with sheet metal shown in Figure 10, sheet metal shown in Figure 12 can be eliminated the waste of a sheet metal basically.
Although terminal member 3 and chain reed 4 are discrete in the present embodiment, terminal member 3 chain reeds 4 can be formed on on a slice, for example, and as shown in figure 13.
Although in the present embodiment, main body 10 front surfaces have rib 15, it is used for putting, and inserted sheet puts the suffered power of reed when flat inserted sheet 21 is inserted into housing 1, each brace 24 can have protruding rib 28 to main body 10, the end of each rib 28 is connected to the front surface of the main body 10 shown in Figure 14 A. as selection, as shown in Figure 14B, main body 1 can have thereon rib 15 at front surface, and each brace 24 can have rib 28, and rib 28 and put at inserted sheet corresponding to the rib 15 of rib 28 can contact with each other when reed 2 is inserted into housing 1. in the example shown in Figure 14 B, preferably in the rib 15 of main body 10, form groove 16, the rib 28 of brace 24 is inserted in the groove 16, shown in Figure 15 A. perhaps shown in Figure 15 B, the rib 28 of preferred brace 24 has groove 29, and the rib 15 of main body 10 is inserted in the groove 29. in these examples, can prevent that inserted sheet from putting reed 2 and moving along the direction vertical with housing 1 longitude.
Although a reed 21 has opening 27 to realize two contact structures in the present embodiment, reed 21 does not certainly have opening.In this embodiment, also preferably at the limit sheet to the distance D 1 of 23 free-ended reeds between to 21 than narrow, as shown in figure 16 in the distance D 2 of brace end between them.
Although the socket in the present embodiment is a wall socket, socket of the present invention is not limited to wall socket.Socket for example of the present invention can be used for socket bar (power strip in other words).
Figure 17 is a kind of optional form that the inserted sheet of present embodiment puts reed.Put in the reed at this optional inserted sheet, the limit sheet of framework 22 folds back to 23, so limit sheet 23 and reed are arranged in the elongated row 21.The limit sheet is connected to each other to the brace 24 under 21 by reed to 23.The limit sheet can use brace 24 sides to be connected to each other to 23.Put in the reed at this optional inserted sheet, because limit sheet 23 and reed are arranged in the elongated row 21, the contact point that flat inserted sheet 210 and inserted sheet put reed 2 is moved backward, as shown in figure 18.As a result of, having socket that this optional inserted sheet puts reed also can put under reed chucking power and the situation that is connected pressure and prevent accidental shock not reducing inserted sheet.
